<P>PROBLEM TO BE SOLVED: To provide a method and a device to compute the combiner coefficients for a space-time solution of a wireless communication system. <P>SOLUTION: Weights of signals are adjusted using known a priori that is time-division-multiplexed with other signals such as a pilot signal etc. in a high data rate HDR system in which signals are transmitted at full power. The MMSE (minimum mean squared error) method is applied, which enables weight combination on a path-by-path base. The weight is computed as a function of a noise correlation matrix and a spatial signature per path. The noise correlation matrix is computed from an autocorrelation matrix of the received signal. In one embodiment, the MMSE method is applied in such a way that the MMSE method uses a non-time-gated pilot signal. <P>COPYRIGHT: (C)2010,JPO&INPIT |
